Transponder Installation & Programming
Installation
1. Prior to removing the existing index and index cover, verify that the
transponder style is compatible with the meter style.
2. Verify that the battery is properly seated, and that the battery wires
are flush to the left side of the transponder wall (facing the rear of the
transponder).
Note: When transporting transponders to the field for
installation please take care not to jar the housing and dislodge the
battery from the bracket.
3. Verify that the transponder is in good working order by querying the
transponder for the meter reading using an SRP, PI, or any other
appropriate interrogation device.
4. If the transponder is in good working order, remove the existing
index and index cover from the meter. Remove the gasket and any
adhesive material from the meter – a scraper or putty knife is
recommended for this task.
5. Using the self-tapping index screws provided, mount existing index
to the transponder, verifying that the index wriggler is properly mated
with the transponder wriggler.
6. Mechanical Check
a. Once the index is attached to the transponder, perform a quick
spin test to verify that the index rotates freely and without
resistance. If the index is rotated 3 times in the clockwise
direction, be sure to rotate it 3 times in the counter-clockwise
direction to assure that no additional subcounts or counts are
inadvertently placed on the mechanical index. Subcounts added
to the e-index during this procedure will be cleared when the
transponder is programmed to the mechanical index reading.
7. Sub-Count Check
a. Rotate the transponder wriggler such that the drive dial is in the
12 o’clock position.
b. Read the transponder subcounts using an SRP, making note of
the subcount value.
c. While facing the index rotate the drive dial 3 times in the counter-
clockwise direction, stopping at the 12 o’clock position.
d. Read the transponder subcounts using an SRP, making note of
the new subcount value. The new subcount value should read 3
subcounts higher than the original reading. If the new subcount
value is less than the original subcount value, please consider
